Monocular Pose Estimation For Automated Aerial Refueling Via Perspective-N-Point, James C. Lynch

Theses and Dissertations

Any Automated Aerial Refueling (AAR) solution requires the quick and precise estimation of the relative position and rotation of the two aircraft involved. This is currently accomplished using stereo vision techniques augmented by Iterative Closest Point (ICP), but requires post-processing to account for environmental factors such as boom occlusion. This paper proposes a monocular solution, combining a custom-trained single-shot object detection Convolutional Neural Network (CNN) and Perspective-n-Point (PnP) estimation to calculate a pose estimate with a single image. This solution is capable of pose estimation at contact point (22m) within 7cm of error and a rate of 10Hz, regardless of …

An Exploratory Study Of General Aviation Aircraft Magneto Ignition System Failures, Gregory Alexander Damien Fox

Theses and Dissertations

This ex-post-facto, archival, single-case, research study explored early failures of magneto ignition systems in the training aircraft fleet operated by FIT Aviation, LLC (FITA). In 2012, an increasing number of early magneto failures prompted FITA to outsource the overhaul work to a specialty overhaul provider. Despite contracting out the overhauls, the early magneto failures continued to increase. Archival data, from the beginning of 2007 through the first quarter of 2017, came from engines logbooks associated with 48 Piper aircraft. Archival data were grouped into four categorical variables by aircraft type. A total of 518 magnetos, separately mounted as left or …

Intention To Complain About Unmanned Aircraft System Noise: A Structural Equation Analysis, Robert Brents

Doctoral Dissertations and Master's Theses

Aircraft noise has a long and documented history as a source of public annoyance and a driver of noise complaints. The impending large-scale use of unmanned aircraft systems (UAS)s could expose a broader cross-section of the public to a new type of aircraft noise. Recent research notes some reactions to UAS noise, but no rigorous analyses of public intention to complain about UAS noise have been found.

Due to the potential proliferation of UASs and their attendant noise, understanding public reaction could advise both government and industry. Governments at all levels could apply the results to inform policies related to …

Biology Faculty Publications

Unmanned aerial vehicles (UAVs) have become a popular wildlife survey tool. Most research has focused on detecting wildlife using UAVs with less known about behavioral responses. We compared the behavioral responses of breeding blue-winged teal (Spatula discors) (n = 151) and northern shovelers (Spatula clypeata) (n = 46) on wetlands flown over with a rotary DJI Matrice 200 quadcopter and control wetlands without flights. Using a GoPro camera affixed to a spotting scope, we conducted focal individual surveys and recorded duck behaviors for 30 minutes before, during, and 30 minutes after UAV flights to determine if …

Resilience Attributes Of Certificated Flight Instructors, David Cross, Kristine Kiernan

Publications

The aviation industry has extensive vocabulary, data sources, and theoretical models to investigate human errors. However, the industry does not have commensurate ways to think about and analyze human success. Learning from successful routine operations is challenging because the corresponding common language and data streams are less robust. This paper explores the use of the critical incident debrief method to collect data on routine resilient performance among Certificated Flight Instructors (CFI). CFI thoughts and behaviors were coded in accordance with resilience theory. The critical incident debrief method is a valuable source of data for exploring resilient performance as it provides …

Characteristics Of Unmanned Aircraft System (Uas) Sightings And Airport Safety, Cheng Wang, Sarah M. Hubbard

Journal of Aviation Technology and Engineering

This paper presents the characteristics of unmanned aircraft system (UAS) sightings and discusses these characteristics in the context of airport safety using airport operational data. An unmanned aircraft in the vicinity of a commercial airport may be a potential threat to aircraft operations, and may result in operational and economic impacts if it causes an airport delay or shutdown. To ensure a record of UAS activity, the Federal Aviation Administration collects and publishes a UAS Sightings Report. This study analyzed UAS sightings and found that they vary by time of year and time of day, with more sightings in the …

Female Relief Systems In U.S. Military Fighter Ejection Seat Aircraft, Marian C. Schultz, James T. Schultz, Joshua J. Schultz

Journal of Aviation Technology and Engineering

In early aircraft, the amount of fuel the aircraft could carry usually determined how long it could stay in flight. Today, with aircraft being able to air refuel, the time they are able to stay aloft is based more on human needs, one being waste management. Voiding urine in a single-seat ejection seat aircraft has been an issue for male pilots in the past, but with the increasing numbers of female pilots in single-seat aircraft, finding a solution has intensified. This paper reviews the various methods that are available for both male and female pilots, including the newest method which …

Cfis’ Safety Behaviors At Flight Training Schools: Understanding The Effects Of Personality Traits, Self-Efficacy, Risk Perception, And Safety Climate, Vivek Sharma, Meredith Carroll

Aeronautics Faculty Publications

According to Aircraft Owners Pilot Association [2], approximately 63% of the accidents involving certified flight instructors (CFIs) occurred during advanced training, which involves low altitude operations, critical decision-making skills, and accurate judgement. Research in the past has demonstrated that pilots’ safety behaviors also predict their involvement in an accident or incident [6]. Many studies across various work domains have examined how factors such as personality traits, perceived risk, safety climate, and self-efficacy influence safety behaviors [1][3][4][5][6][7][8]. Studies have found that personality traits such as Conscientiousness, Extraversion, Openness, and Agreeableness were positively related to safety behaviors [3][7][11], whereas Neuroticism was negatively …

Timestamp Estimation From Outdoor Scenes, Tawfiq Salem, Jisoo Hwang, Rafael Padilha

Annual ADFSL Conference on Digital Forensics, Security and Law

The increasing availability of smartphones allowed people to easily capture and share images on the internet. These images are often associated with metadata, including the image capture time (timestamp) and the location where the image was captured (geolocation). The metadata associated with images provides valuable information to better understand scenes and events presented in these images. The timestamp can be manipulated intentionally to provide false information to convey a twisted version of reality. Images with manipulated timestamps are often used as a cover-up for wrongdoing or broadcasting false claims and competing views on the internet. Estimating the time of capture …

Drone Cage Design And Implementation To Enable Small Drone Architecture Testing, Marco Fagetti, Emily M. Suh

Undergraduate Student Works

Geometric mechanics is a dynamical formalism that allows for simultaneous treatment of rotational and translational motion without the drawbacks of attitude parameterization sets. While geometric mechanics is well suited to deal with full six degree-of-freedom motion or significant position-attitude coupling, this formalism has yet to be extensively applied to hardware systems. The broader research goals of this work aim to prove the practical viability of this theoretical framework by applying it to a class of Crazyflie drones, which are frequently used to assess Guidance, Navigation, and Control schemes. To efficiently achieve these goals, a reliable, collapsible drone cage is required …
